TensorFlow creates a classifier and tensorflow implements classification.
The examples in this article share the code used to create a classifier in TensorFlow for your reference. The details are as follows:
Create a classifier for the iris dataset.
Load the sample data set and implement a simple binary classifier to predict whether a flower is an iris. There are

Use tensorflow to build CNN and tensorflow to build cnn
Convolutional Neural Networks Convolutional Neural Network (CNN) transfers the data of an image to CNN. The original coating is composed of RGB, And then CNN thickened the thickness and the length and width become smaller, each layer is stretched to form a classifier.
There are several important concepts in CNN:
Stride
Padding
Pooling

TensorFlow is used for simple linear regression and gradient descent examples. tensorflow gradient
Linear regression is supervised learning. Therefore, the method and supervised learning should be the same. First, a training set is given and a linear function is learned based on the training set, then, test whether the function is trained (that is, whether the function is sufficient to fit the training set

Mnist is an entry-level computer-vision dataset that contains 60,000 training data and 10,000 test data. Each sample is a variety of handwritten digital pictures below:
It also contains the corresponding label for each picture, telling us this is a number. For example, the above four pictures are labeled 5,0,4,1.

1. Overview
As with the old version of TensorFlow, the model needs to be saved, and this preservation is cyclical. Because in many cases the gradient will swing around the local minimum, that is to say, in many cases, the last training model is not necessarily optimal.
2. Save the Model
We can create a location where the checkpoint is saved when we build the model, and we can start by creating a folder with the following command.
You can add paramet

1. Overview
A feature column is a bridge between the original data and the model. In general, the essence of artificial intelligence is to do weights and offset operations to determine the shape of the model.
Before using the TensorFlow version, the data must be processed in a kind and distributed way before it can be used by the artificial intelligence model. The appearance of feature columns makes the work of data processing much easier. 2, the fun
In general, there are two functions for printing tensorflow variables:tf.trainable_variables () and Tf.all_variables ()The difference is:Tf.trainable_variables () refers to the variables that need to be trainedTf.all_variables () refers to all variables
In general, we are more concerned with training variables that need to be trained:It is important to note that the entire graph is initialized when the variable name is output

November 9, 2015 Google Open source of the artificial intelligence platform TensorFlow, but also become the 2015 's most popular open source projects. After 12 iterations from v0.1 to v0.12, Google released its version of TensorFlow 1.0 on February 15, 2017, and hosted the first TensorFlow Dev Summit conference in Mountain View, California, USA.
1. Introduction
The expansion pack can generate a file that the IDE can understand to provide accurate auto-completion functionality. This generated file is based on the files that exist in the project, so it is always real-time. Of course, if you don't want to generate this file manually, you can also use the pre-generated files and put them in the project root directory (these files are less real-time):
